An enhancement at the SIGMA$\overline{K}$ threshold (1680) MeV observed in K$^{-}$p reactions at 4.2 GeV/c
An enhancement in the ( Sigma K) mass spectrum at threshold is observed in K/sup -/p interactions at 4.2 GeV/c. It appears both in the neutral and negative charge states. Corresponding Lambda K mass distributions show weak evidence for an effect close to this threshold ( approximately 1680 MeV). Alt...

| description | An enhancement in the ( Sigma K) mass spectrum at threshold is observed in K/sup -/p interactions at 4.2 GeV/c. It appears both in the neutral and negative charge states. Corresponding Lambda K mass distributions show weak evidence for an effect close to this threshold ( approximately 1680 MeV). Although the interpretation of the ( Sigma K) enhancement by itself is ambiguous, a ( Sigma K)-( Lambda K) coupled channel analysis gives results compatible with its interpretation as a new Xi *.
